When things finally cooled enough for the first hydrogen atoms to form, the Universe swiftly became transparent. Is our universe infinite in size and contents? The universe is finite. But I always say that we don't know for sure that this happened. However, scientists think that the universe is flat like a pancake. Both possibilities have mind-bending implications. – user2735 Nov 26 '12 at 22:09 If the universe is infinite, and there is a possibility different from zero for us to find ourselves not been contacted by our doppelgänger yet, then that scenario is happening just right now, with 100% of certainty. Morning Edition is asking questions about the universe, part of an effort to put things in perspective. But in CCC, it never goes through a period of contraction â it only ever expands.Â, âThe view I have is that the Big Bang was not the beginning,â says Penrose. Khan Academy is a 501(c)(3) nonprofit organization. But even with tweaks like this, inflation makes predictions that have, at least thus far, not been confirmed. However, due to the inflation of the universe, as well as the apparently accelerating expansion of every observable corner of the universe, the most distant light we have been able to detect is from roughly 46 billion light-years in every direction.  An actual, or completed, infinity seems to be literally a contradiction in terms; it seems to entail an end of something without an … In some variations, an infinite number of universe histories occur simultaneously at great distances from one another. If the end of the universe is the big freeze then it could prove that yes the universe us infinite. Steinhardt, who was one of the original architects of inflationary theory, ultimately got fed up with the lack of predictiveness and untestability. Our observableuniverse expanded from one tiny homogenous region within that primordial hot mess, producing the uniform CMB. However, in an infinite and eternal universe, it could be possible that an exact remake of your consciousness is created, which would allow you to live again, according to Mr Jacholkowski. Or, the Big Bang might be a transition point in a universe that has always been â and always will be â expanding. “Inflation says there’s a multiverse, that there’s an infinite number of ways the Universe might come out, and we just happen to live in the one that is smooth and flat. Both possibilities have mind-bending implications. âI always regarded inflation as a very artificial theory,â says Roger Penrose, emeritus Rouse Ball professor of mathematics at Oxford University. Because we live in three dimensions, 250 times the radius means (250) 3 times the volume, or more than 15 million times as much space. Space is black & you can only see so many stars. Lets say the numbers 1-19-23-45-46-53 are the numbers that popped out of the lotto machine. Sometimes it's too weak, and the universe implodes again before anything can form. One of the predictions of CCC is that there might be a record of the previous aeon in the cosmic microwave background radiation that originally inspired the inflation model. A universe smaller than the observable.

What would an Infinite Universe Mean? âThe hope is not necessarily that we're going to see the beginning more directly, but that maybe through some roundabout way we'll better understand the structure of physics itself.â. For example, take lotto numbers. “Hopefully it will be possible in the future to clone our minds but it is rather a kind of science fiction as this cloning will be never perfect due to possible quantum processes in our minds, impossible to reproduce. Posted by. If the Universe is infinite, does that mean we'll eventually do this all over again? Quantum physics also forces inflation theories into very messy territory. For starters, the fact that we know the observable universe to be 93 billion light-years across is astonishing — that’s a great story in itself, and you can read about it extensively here — but how do we know it? And it is these that make up dark matter, according to those who support the Mirror Universe theory. The Earth seemed flat because it looked so big.
